Image signal recording device

1. An image signal recording device comprising: a remaining amount detecting processor that detects a remaining amount of a recording medium, which is recordable; a recording processor that records only a part of a single image in the recording medium, when the remaining amount is less than a recording capacity necessary to record an image signal corresponding to the single image; and an indicating processor indicating an image area, corresponding to said part of the single image, on a surface of a display device.

2. An image signal recording device comprising: a remaining amount detecting processor that detects a remaining amount of a recording medium, which is recordable; and a recording processor that records only a part of a single image in the recording medium, when the remaining amount is less than a recording capacity necessary to record an image signal corresponding to the single image; wherein the part of the single image is recorded in a recording area having a size approximately equal to the remaining amount.

3. An image signal recording device according to claim 1, further comprising an image area selecting processor selecting said part of said single image based on an image area included in said single image.

4. An image signal recording device according to claim 1, further comprising a compression ratio setting processor setting a compression ratio of an image signal which is to be recorded in said recording medium, said recording processor recording said part of said single image in accordance with said compression ratio.

5. An image signal recording device according to claim 1, further comprising a comparing processor comparing said recording capacity with said remaining amount.

6. An image signal recording device according to claim 1, wherein said recording processor records said image signal in said recording medium without compressing said image signal, when said recording capacity is less than or equal to said remaining amount.

7. An image signal recording device according to claim 1, wherein said recording processor divides said remaining amount into a plurality of uniform recording areas and records said part of said single image in one of said plurality of uniform recording areas.

8. An image signal recording device comprising: a remaining amount detecting processor that detects a remaining amount of a recording medium, which is recordable; a compression ratio setting processor that sets a compression ratio of an image signal which is to be recorded in the recording medium; and a recording processor that records only a part of each of (N+.alpha.) number of images in the recording medium, when the remaining amount is less than a recording capacity necessary to record image signals, which correspond to N number of images and are compressed in accordance with the compression ratio, each of N and .alpha. a positive integer; wherein the parts of the images are recorded in a recording area having a size approximately equal to the remaining amount.

9. An image signal recording device according to claim 2, further comprising an image area selecting processor selecting the part of the single image based on an image area included in the single image.

10. An image signal recording device according to claim 2, further comprising a compression ratio setting processor setting a compression ratio of an image signal which is to be recorded in the recording medium, the recording processor recording the part of the single image in accordance with the compression ratio.

11. An image signal recording device according to claim 2, further comprising a comparing processor comparing the recording capacity with the remaining amount.

12. An image signal recording device according to claim 2, wherein the recording processor records the image signal in the recording medium without compressing the image signal, when the recording capacity is less than or equal to the remaining amount.

13. An image signal recording device according to claim 2, wherein the recording processor divides the remaining amount into a plurality of uniform recording areas and records the part of the single image in one of the plurality of uniform recording areas.
